Two new Gloeoporus species, G. citrinoalbus and G. hainanensis spp. nov., are described from Hainan Island, tropical China, based on morphological and molecular characters. G. citrinoalbus is characterized by a lemon yellow pore surface, white margin of the fresh fruiting body, tiny pores (8–10 per mm), a monomitic hyphal system with clamped generative hyphae, presence of gloeocystidia, and allantoid basidiospores measured as 3.5–4 × 1 μm. G. hainanensis is characterized by white to cream pore surface, tiny pores (9–11 per mm), a monomitic hyphal system with simple septate hyphae, and allantoid basidiospores measured as 3.5–4.5 × 1 μm. Both morphological characters and phylogenetic analysis inferred from ITS and nLSU sequences confirmed the placement of the two new species in Gloeoporus and showed their relationships with similar species in the genus.
